+completable values for any facet. You can retrieve the search query as a

+      enhances ordinary search boxes with the ability to autocomplete
+      faceted search queries. Specify the facets for completion, along with the
+      completable values for any facet. You can retrieve the search query as a
+      structured object, so you don't have to parse the query string yourself.

+      enhances ordinary search boxes with the ability to autocomplete
+      faceted search queries. Specify the facets for completion, along with the
+      completable values for any facet. You can retrieve the search query as a
+      structured object, so you don't have to parse the query string yourself.

+
+    <p>
+      <b class="header">0.2.1</b> <i>November 14th, 2011</i><br />
+      The autocompleted facets and values that are provided by your callbacks <tt>facetMatches</tt>
+      and <tt>valueMatches</tt> can now preserve the order of items you give them. Simply pass an
+      options hash with <tt>preserveOrder: true</tt> as the second argument to the callback. See
+      <a href="demo.html">the demo page</a> for an example.
+    </p>
+    <p>
+      <b class="header">0.2.0</b> <i>August 10th, 2011</i><br />
+      Multiple instances of VisualSearch on a single page. <tt>VS.init</tt> now returns
+      a reference to the instance. The <tt>search</tt> callback now contains both the
+      serialized search query and a reference to the search query collection (as a 
+      <a href="http://documentcloud.github.com/backbone/#Collection">Backbone.Collection</a>), 
+      which can be used to manipulate each facet directly. See 
+      <a href="docs/search_query.html">the source code for search_query.js</a> for available 
+      methods on the collection.
+    </p>
+    <p>
+      <b class="header">0.1.0</b> <i>June 23rd, 2011</i><br />
+      Initial release of VisualSearch.js.
